Research findings on Heavy metal analysis have shown seasonal variations in heavy metal concentration in groundwater of Kangra district, H.P., India, consecutively for both years (2014-2016). Groundwater samples were collected during Pre-monsoon, Rainy and Post-monsoon seasons for two years from 2014-15 & 2015-16 from the selected 17 sampling spots of kangra district. Heavy metals viz. B, Fe, Zn, Mn, Pb, Cu, Ni, Cr & Cd were estimated by using atomic absorption spectroscopy. Groundwater samples from seventeen prominent sampling spots of Kangra district were analysed for seasonal variations for two years. During these investigations, no traces of Copper (Cu), nickel (Ni), Chromium (Cr) and Cadmium (Cd) were found at selected sampling spots during all seasons. Significant variations were observed in concentration of B, Fe, Zn & Mn among most of the sampling spots during all the seasons at 5% level of significance (<0.05) consecutively for both years. Though the heavy metal concentration was found to be within permissible limits; yet increasing concentration of B, Fe & Zn in drinking groundwater could pose a serious threat on public health in the coming years. Correlation coefficient were also analysed to find out the correlation among various heavy metals studied.
